Has anyone swapped the speedometer on a 2005? The needle works when the car is cold-soaked, but not when it warms up. The odometer works, as do the other LCD functions.

Is the speedo a module, or do I have to swap the whole cluster?

How much trouble is it to swap the cluster? Are there things that have to be programmed?

 

Expect to get anti-theft (at best) unless you only swap physical things like the motor driving the needle or the needle.

 

The instrument cluster, engine control module and key-fob are the "key" points of the X-Type anti-theft system.
IDS/SDD is required to reprogram the VIN for an IPC swap. It's been awhile, but I think that IPC reprogram can be done without IDS/SDD "golden-key" access.
Not so for engine control module. However, an X-Type "parts-car" can be activated by swapping all three but the VIN will be wrong for the car.

 

Can just the speedo module be swapped, without doing the whole cluster?

 

There is no reason you cannot swap out the speedo "stepper motor" if you think that has failed. If you have a donor cluster to take one off it should be simple desolder, unclip and replace.
But you might just want to do some resistance checks first between the motor winding pins of the donor motor and your suspected faulty motor first to see if you can detect an open winding.
It is likely a 2 or 3 pole stepper motor (the more poles, the finer the rotation increments), so expect four to six pins and two or three separate windings.

If all the poles windings are there, then your issue might be the stepper motor driver IC.
As long as that is separate from the processor IC, it is likely a non-keyed device just receiving serial data instruction from the CPU and should be able to be replaced without any programming.

 

Sone, before you start replacing parts and/or the whole instrument cluster, you will see that there is a main harness that feeds the instrumnet cluster. Look at the back side of the board from the plug. You will see where the plug gets soldered to the board. Inspect those solder joints closely. If you see a very fine black crack (looks like a very fine hair) that is encircling the post, that is your problem. A touch with a hot iron to remelt the solder will most likely fix your issue. Just because you find one cracked solder joint, inspect all of them. You may find more than one needing some touch up. If you do not find any solder joints, then move on to replacing the stepper motor and/or the whole instrument cluster. But, like was said, if you do the instrument cluster, then you have to get it programmed to work with your keys and ECU.
